Part Number: ADS7828 Hi,
the read data of the ADS7828 is always 0x0 on every channel. (All Channels are connected to Voltages I can measure on the Inputs to the IC)
Here is the protocol:
Red = SCL
Blue = SDA
Green = Tristate activated
Yellow…
Part Number: ADS7828 Can you provide the typical analog input channel's input impedance range for the allowable range of sampling rates for the ADS7828?
I greatly appreciate the support.

Part Number: ADS7828 Tool/software: There is no local reset for this I2C I/O expander. I am planning to pull the VCC low momentarily in case there is a latchup in the I2C communication. Is this an issue if the SDA/SCL and input pins are driven? Do I have…
Part Number: ADS7828 Other Parts Discussed in Thread: ADS7830 , ADS1115 , ADS112C04 Hi
We are thinking about using the ADS7828E ADC to measure the voltage of electrochemical air sensors. These sensors generally output voltage below 1V.
Is there…
Part Number: ADS7828 Hi,
The customer has three Power Supplies (Sources).
I am thinking about the following connection, but is it possible to measure Sources 2 and 3 with pseudo differential input?
GND1, 2 and 3 are isolated.
Best Regards, …
Part Number: ADS7828 I am using smbus on RaspberryPi4 to read number off of ADS7828.
I write 0x48, 0x84 to read Ch0 in single ended mode.
I can't read read other Channels using the same scheme. When I try reading the Ch1 for example (using 0x48…
Part Number: ADS7828-Q1 Hi,
The absolute maximum rating listed in the datasheet of ADS7828-Q1 for the input pins is as below -
Digital Input Voltage to GND ................................. –0.3V to +VDD + 0.3V.
When the ADC is OFF (not powered…
Part Number: ADS7828 Hello,
We are using an external reference of 3.3V. In the datasheet, it is specified that the measurement range is from 0V-VDD when using an external reference. However, we do not read the maximum value of bits (4095) when connecting…
Part Number: ADS7828-Q1 Other Parts Discussed in Thread: ADS7823-28EVM , ADS7828 I am experiencing a strange behavior on my own design with ADS7828EIPWRQ1, and have been able to replicate the issues using TI's evaluation board model ADS7823-28EVM. I am…
Part Number: ADS7828
We are using the smbus2 library in Python to read data coming originally from a TMSC1108-Q1 current sensor (analog) which is sent through an ADS7828 ADC and communicated to a Raspberry Pi via I2C protocol . We defined an array of…
